I dont know where I stand with these damn opk's. I've been worryig coz they haven't showed up my surge this month. Then today I done one an hour ago, again nothing, left it on my dressing table and went back 5 mins later and it had a faint line. So though hmm, looked in the bin which has the last few days in there and theres some with lines, faint and strong and others that are blank. Now I'm thinking they arn't like last months ones that showed up straight away, I'm thinking they should of been left for a few mins before reading. So I'm now classing it as the last 2 days having positive readings and changed my chart with FF but I felt like I ov'd yesterday with cramps but have wet cm today. I'm so confussed
